parallel-planed tuffite alternating witli blackisli bands of dirt bed 

 and carbonized wood *\ These liave tlie appearance of Tertiary 

 rocks. They are overlaid and partly underlaid by breccia and a 

 fiow of masanite. A pointed hill, Yv-dal-san'"^, on tlie eastern 

 foot of which is located oni- Consulate (PI. JX. pg. 3, and PI. X.

 like rhyolite for which it is often mistaken. It presents various
